WHAT IT DOES

What pair_ledger_tron does on VaultPilot MCP

AI agents call pair_ledger_tron to retrieve information from VaultPilot MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`accountIndex`	integer	—	Ledger TRON account slot (hardened BIP-44 account index). 0 = first account, 1 = second, etc. — same convention Ledger Live uses. Omit to pair the default accou

Parameters from the server's own tool schema.

RISK

Why pair_ledger_tron is rated Low

The primary action is reading a public address from the Ledger hardware device and caching it for status reporting. It does not sign transactions, move funds, or modify any data destructively.

From the tool's definition Reads the device address at m/44'/195'/<accountIndex>'/0/0 (default accountIndex=0) and caches it so `get_ledger_status` can report it.

RECOMMENDED RULE

The rule that runs pair_ledger_tron safely

PolicyLayer is an MCP gateway: it sits between your AI agents and VaultPilot MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pair_ledger_tron, this is the rule to start with:

pair_ledger_tron Allowed

pair_ledger_tron is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect VaultPilot MCP, apply this rule, and every pair_ledger_tron call is checked against it from then on.

FAQ

Questions about pair_ledger_tron

What does the pair_ledger_tron tool do? +

Pair the host's directly-connected Ledger device for TRON signing. REQUIREMENTS: Ledger plugged into the machine running this MCP (USB, not WalletConnect), device unlocked, and the 'Tron' app open on-screen. Ledger Live's WalletConnect relay does not currently honor the tron: CAIP namespace, so TRON signing goes over USB HID via @ledgerhq/hw-app-trx. Reads the device address at m/44'/195'/<accountIndex>'/0/0 (default accountIndex=0) and caches it so get_ledger_status can report it. Call multiple times with different accountIndex values (0, 1, 2, …) to pair additional TRON accounts — each call adds to the cache; subsequent calls for the same index refresh in place. Call this once per session (per account) before calling any prepare_tron_* tool or send_transaction with a TRON handle. If the TRON app isn't open, or the device is locked, returns an actionable error describing what to fix. It is categorised as a Read tool in the VaultPilot MCP MCP Server, which means it retrieves data without modifying state.

What parameters does pair_ledger_tron accept? +

pair_ledger_tron accepts 1 parameter: accountIndex. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on pair_ledger_tron? +

Register the VaultPilot MCP server in PolicyLayer and add a rule for pair_ledger_tron: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches VaultPilot MCP. Nothing to install.

What risk level is pair_ledger_tron? +

pair_ledger_tron is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit pair_ledger_tron? +

Yes. Add a rate_limit block to the pair_ledger_tron rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block pair_ledger_tron completely? +

Set action: deny in the PolicyLayer policy for pair_ledger_tron. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides pair_ledger_tron? +

pair_ledger_tron is provided by the VaultPilot MCP server (vaultpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
